Slot Antennas For Dual And Wideband Operation In Wireless Communication Systems
نویسندگان
چکیده
Two antenna designs were achieved for dual and wide band operation in wireless systems. One design was realized using a tapered meander slot with a microstrip feed to give dual band operation at 1.8 and 2.4 GHz. In this design both operating frequencies are controlled mainly by the horizontal slot width of the meander and the distance of the microstrip line termination from the slot. The other design was accomplished by the use of a coplanar patch-slot antenna (CPA) fed by a coplanar waveguide (CPW). This later design is easily tuned to operate at 2.45 and 5.75GHz, with wide bandwidth (BW). The operating frequency is controlled by modifying the patch dimensions. Return loss, input impedance, radiation pattern, directivity, gain and efficiency of the proposed designs are computed and presented.
